The first element of South Croxton, in the East Goscote Hundred of Leicestershire, likely comes from the Old Danish male personal name Krōk (Old Norse Krókr), originally a byname meaning ‘crooked-back’, or possibly ‘crooked-dealer’ related to Old Norse krókr ‘hook’. Alternatively the first element could be Old English crōc ‘a crook’, that is relating to a location situated in a nook or bend of land. The second element is Old English tun ‘an enclosure; a farmstead; a village; an estate’. The affix suð ‘south’ distinguishes South Croxton from Croxton Kerrial in the Framland Hundred.
